无线通信的方法及系统 Method and system for wireless communication

技术领域 FIELD

[0001] 本发明涉及无线通信,更具体地说,涉及一种改变多线共存中的从属帧的优先级的方法和系统。 [0001] The present invention relates to wireless communications, and more particularly, to a method and to change the priority system slave frames in multiwire coexistence.

背景技术 Background technique

[0002] 众所周知,某些常规的通信系统用于在无线和/或有线通信设备之间提供无线和有线通信。 [0002] is well known, some conventional communication system for providing wireless and wireline communication between wireless and / or wire lined communication devices. 这些通信系统包括国内和/或国际蜂窝电话系统和互联网、以及点对点家庭无线网络。 These communication systems include national and / or international cellular telephone systems and the Internet, as well as point to point wireless home network. 每种类型的通信网络都根据相关通信标准进行设计并得以运作。 Each type of communication networks are designed according to the relevant standards and communication operations. 例如,无线通信系统可根据下述一项或多项标准来运营,包括但不限于IEEE 802. 11、蓝牙、高级移动电话服务(advanced mobile phone service,简称AMPS)、数字AMPS、全球移动通信系统(Global System of MobileCommunication,简称GSM)、石马分多址(code division multipleaccess,简称CDMA)、本地多点分配业务(local multi-point distribution system,简称LMDS)、多信道多点分配系统(multi-channel multi-point distribution system,简称MMDS)、和/或它们的变更标准。 For example, wireless communication systems may operate according to one or more of the following criteria, including but not limited to, IEEE 802. 11, Bluetooth, advanced mobile phone service (advanced mobile phone service, abbreviated AMPS), digital AMPS, global system for mobile communications system (Global system of MobileCommunication, referred to as GSM), Shima division multiple access (code division multipleaccess, referred to as CDMA), local multi-point distribution services (local multi-point distribution system, referred to as LMDS), multichannel multipoint distribution system (Multi- channel multi-point distribution system, referred to as MMDS), and / or changes thereof criteria.

[0003] 根据无线通信系统的类型,无线通信设备,例如蜂窝电话、对讲机、个人数字助理(PDA)、个人电脑(PC)、膝上电脑或家庭娱乐设备,直接或间接地与其它无线通信设备通信。 [0003] Depending on the type of wireless communication system, wireless communication devices, such as cellular telephones, walkie-talkie, a personal digital assistant (PDA), personal computer (PC), a laptop computer, or home entertainment equipment, either directly or indirectly with other wireless communication device communication. 对于直接通信,也就是点对点通信,参与的无线通信设备将它们的接收器和发射器调整到相同的一个或多个信道,并通过该信道通信。 For direct communications, i.e. point to point communication, wireless communication devices participating in their receivers and transmitters to the same adjustment of one or more channels, and communication through the channel. 每个信道可利用无线通信系统的多个射频(RF)载波中的一个或者多个。 Each channel may utilize a plurality of RF wireless communication system according to one or more (RF) carriers. 对于间接的无线通信,每个无线通信设备通过所分配的一个或多个信道,直接与相关的基站(例如,对蜂窝服务来说)和/或相关的接入点(例如,对室内或建筑内的无线网络来说)通信。 For indirect wireless communications, each wireless communication device via one or more allocated channels, directly with an associated base station (e.g., for cellular services) and / or an associated access point (e.g., indoor or building is within the wireless network) communications.

[0004] 为了使每个无线通信设备都参与无线通信会话,它利用包括接收器和发射器的内置无线电收发器,或者连接到相关的无线电收发器,例如,家庭和/或室内无线通信网络的基站,或者连接到RF调制解调器。 [0004] In order for each wireless communication devices participating in the wireless communication session, which uses built-in radio transceiver includes a receiver and a transmitter, or a connector to an associated radio transceiver, e.g., family and / or indoor wireless communication network base station, or to RF modem. 发射器根据特定的无线通信标准对数据进行调制,从而将数据转换成RF信号。 The transmitter modulates data in accordance with a particular wireless communication standard, thereby converting the data into an RF signal. 但是,不同的通信系统可能使用不同的标准,例如,IEEE 802. 11标准和蓝牙标准,它们可共享相同的RF频谱。 However, different communication systems may use different standards, e.g., IEEE 802. 11 standard and the Bluetooth standard, which may share the same RF spectrum.

[0005] 为了减轻由于与其他通信系统共享RF频谱而引起的信号干扰干扰,蓝牙标准允许跳频,即在各频率上发射信息。 [0005] To mitigate interference due to signal interference shared RF spectrum with other communication systems due, the Bluetooth standard allows frequency hopping, i.e. transmission of information on each frequency. 在这种方式下,所发射信号的能量分散在79个信道的从 In this manner, the energy of the transmitted signal scattered from the channel 79

2. 402GHz到2. 480GHz的RF频谱中,,各信道间隔1MHz。 2. 402GHz RF spectrum in the 2. 480GHz channel spacing ,, each 1MHz. 蓝牙标准允许每秒跳频1600次。 Bluetooth standard allows hopping 1600 times per second. 跳频系统的优点是将信息分散到较宽的频带上。 Advantages of frequency hopping system information is distributed to a wide frequency band. 因此,对于蓝牙系统在跳频中使用的一些频率来说,其他系统使用一部分相同频谱所发射的信号可能表现为噪音。 Thus, for some frequencies used by Bluetooth system in frequency hopping, the other part of the same system using signals emitted spectrum may appear as noise. 类似地,只有部分蓝牙发射信号将干扰其它系统发射的信号干扰。 Similarly, only part of the signal transmitting Bluetooth signals interfere with other systems interference emitted.

[0006] 两个或多个蓝牙设备,最多共八个设备可组成蓝牙微微网(piconet),其中有一个主设备和最多七个从设备。 [0006] two or more Bluetooth devices, up to eight devices can be composed of a total of Bluetooth piconet (a piconet), which has a master and up to seven slave devices. 微微网蓝牙微微网。 Piconet Bluetooth piconet. 微微网蓝牙微微网蓝牙微微网共享公共通信数据信道,该信道现有容量为I兆比特每秒(Mbps),而最高理想值为3Mbps。 Piconet Bluetooth piconet Bluetooth piconet share a common communication data channel, the channel capacity of the existing I megabits per second (Mbps), while the maximum value over 3Mbps. 该数据信道被分割为625微秒的时隙。 The data channel is divided into slots of 625 microseconds. 尽管主设备可发起与任何从设备的交互,但是从设备只能对主设备做出响应。 Although the master device can initiate from any interaction with the device, but can only respond to the master device from the device. 主设备和从设备之间的微微网蓝牙微微网链路可以是同步面向连接(SynchronousConnection Oriented link,简称SCO)链路或者异步无连接(asynchronousconnectionless link,简称ACL)链路。 Piconet master and slave Bluetooth piconet link between the devices may be a synchronous connection oriented (SynchronousConnection Oriented link, referred to as SCO) link or asynchronous connectionless (asynchronousconnectionless link, referred to as ACL) link. 微微网蓝牙微微网可最多支持三条SCO链路,所有其它剩余带宽均会被ACL链路所用。 Piconet Bluetooth piconet can support up to three SCO links, all other remaining bandwidth ACL link will be used.

[0007] 在目前的一些系统中,蓝牙设备可与WLAN设备共享平台,这可被称为共存(coexistence)。 [0007] In some current systems, a Bluetooth device may share the platform with a WLAN device, which may be referred to coexist (coexistence). 例如,诸如蜂窝电话之类的设备可能集成有蓝牙无线电(Bluetoothradio)和无线LAN无线电(Wireless LAN radio)。 For example, such as a cellular phone or the like may be integrated Bluetooth radio devices (Bluetoothradio) and a wireless LAN radio (Wireless LAN radio). 有时蓝牙无线电和WLAN无线电需要同时发射。 Sometimes Bluetooth radio and WLAN radios need to be transmitted simultaneously. 由于蓝牙无线电和WLAN无线电的距离彼此很近,且在相同的频带上运作,因此其中一个无线电的发射可能会干扰另一个无线电的发射干扰。 Since the Bluetooth radio and WLAN radio distance very close to each other and operating in the same frequency band, wherein a radio transmitter thus may interfere with the emission of another radio interference.

[0008] 通过将传统系统与本发明的各方面进行比较,对本领域的技术人员来说,传统和常规方法的更多局限和缺陷会变得明显。 [0008] By comparison with a conventional system aspects of the present invention, those skilled in the art, and a more traditional limitations and drawbacks of conventional methods may become apparent.

具体实施方式 Detailed ways

[0039] 本发明的某些实施例涉及一种改变多线共存中的从属帧的优先级的方法和系统。 [0039] Certain embodiments of the present invention relates to a multi-line changes dependent frame coexistence priority method and system. 从属帧可以是与蓝牙帧相关的时间段,所述蓝牙帧与蓝牙从属通信设备相关。 Slave Bluetooth frame may be associated with the frame period, the frame associated with a Bluetooth slave Bluetooth communication device. 所述方法包括如果在开始当前蓝牙帧之前,蓝牙设备没有向并置WLAN设备断言(assert)优先级,且如果指示至少所述当前蓝牙帧的剩余部分要求高优先级,则向所述并置WLAN设备传送至少所述当前蓝牙帧的剩余部分的高优先级指示信号。 The method comprising if the frame before starting the current Bluetooth, a Bluetooth device is not set asserts WLAN device (Assert), and priority to, and if at least indicative of the remainder of the current Bluetooth frame requires high priority, juxtaposed to the WLAN device transmits at least a signal indicative of the current high priority Bluetooth frame remaining portion. [0040] 在向并置WLAN设备传送高优先级指示信号的过程中,蓝牙设备可解除断言指示蓝牙通信活动的信号。 [0040] In the process of the WLAN device is set to a high priority and transmitting the instruction signal, the Bluetooth device may de-assert signal indicative of the Bluetooth communication activity. 例如,可以在所述蓝牙设备发射数据时的一部分帧之前进行解除断言。 For example, it may be de-asserted before the portion of the frame when said Bluetooth device transmits data. 所述蓝牙设备可断言指示蓝牙通信活动的信号。 The Bluetooth device may assert a signal indicative of the Bluetooth communication activity. 然后蓝牙设备断言指示蓝牙优先级状态的信号和指示蓝牙通信活动的信号。 The signal is then asserted indicating a Bluetooth device Bluetooth priority status signal indicating the Bluetooth communication activity. 在蓝牙设备发送数据包后,蓝牙设备解除断言指示蓝牙优先级状态的信号和/或指示蓝牙通信活动的信号。 After the Bluetooth device transmits a packet, the Bluetooth device asserts a signal indicative of releasing the Bluetooth priority status and / or signal indicates Bluetooth communication activity.

[0041] 多线共存方法可用于方便通信,例如当蓝牙设备配置了WLAN设备且两种设备都需要工作时。 [0041] Multi-line coexistence method may be used to facilitate communication, for example, when a Bluetooth device is configured with a WLAN device and both devices are required to work. 因此,当蓝牙设备要接收和/或发射时,蓝牙设备可向WLAN设备发送信号;而当WLAN设备正在发射时,WLAN设备可向蓝牙设备发射信号。 Thus, when a Bluetooth device to receive and / or transmit Bluetooth device can transmit a signal to the WLAN device; and when the WLAN device is transmitting, the WLAN device may transmit a signal to the Bluetooth device. 蓝牙设备可指示在蓝牙帧中是否需要高优先级。 Bluetooth devices can indicate whether a high priority in the Bluetooth frame. 高优先级指示允许蓝牙传输,而不受同时WLAN传输的干扰。 High priority indication allows Bluetooth, WLAN without simultaneously interfering transmissions. 但是,通常需要在帧开始前做出指示。 Generally, however, it needs to be made before the start of frame indication.

[0042] 因为蓝牙通信可由蓝牙主设备发起,所以蓝牙主设备可确定帧是高优先级还是低优先级蓝牙主设备。 [0042] Since the Bluetooth communication device may initiate a Bluetooth master, the master Bluetooth device may determine that the frame is high priority or low priority Bluetooth master. 但是,如果帧应该是高优先级帧,从设备并不总是能够在帧之前作出指·示。 However, if the frame should be a high priority frame, from the device is not always able to make the frame before the finger-shows. 在某些时候,蓝牙从设备能够确定帧在何时是高优先级帧。 At some point, the Bluetooth device is able to determine from the frame when the frame is a high priority. 例如,当同步面向连接(SCO)链路处于活动状态(active)时,用于SCO数据传输的帧是高优先级帧,这是由于声音是通过SCO链路传输的。 For example, when a synchronous connection (SCO) link is active for (Active), SCO frames for the data transmission frame is a high priority, since the sound is transmitted via the SCO link. SCO帧可以是每个帧,每隔一个帧,或者每隔两个帧。 SCO frame may be every frame, every other frame or every two frames.

[0043] 但是,通常,蓝牙设备不能确定帧是否是高优先级。 [0043] However, in general, a Bluetooth device can not determine whether the frame is a high priority. 因此,蓝牙从通信设备不能发射及时的应答,因为WLAN设备可能正在发射。 Therefore, the Bluetooth device can not transmit from the communication and timely response, because the WLAN device may be emitted. 本发明的一实施例允许在当前帧已经开始之后,向WLAN设备传送当前帧的高优先级指示信号。 An embodiment of the present invention allow the frame after the current has started, the current frame is transmitted to the WLAN device a signal indicating a high priority. 用这种方式,蓝牙从通信设备可发射及时的应答,而不受到WLAN设备的干扰。 In this manner, from the Bluetooth communication device may transmit a response in a timely manner, without interference of the WLAN device.

[0044] 图I是可与本发明的实施例结合使用的蓝牙微微网的示意图。 [0044] FIG. I is a schematic diagram of a Bluetooth piconet may be used in connection with the embodiment of the present invention. 参照图1,示出了个人电脑(PC) 100、膝上电脑110、以及个人数字助理(PDA) 120。 Referring to Figure 1, there is shown a personal computer (PC) 100, laptop computer 110, and a personal digital assistant (PDA) 120. 这三个主设备或者主平台,每一个均可支持蓝牙。 The three master or the main platform, each of which can support Bluetooth. 每个主设备可以有蓝牙应用程序和蓝牙通信设备,用于发送和接收信号。 Each master device may have a Bluetooth application and a Bluetooth communication device for transmitting and receiving signals. 然后每个主设备都可被认为是蓝牙设备。 Then each master device can be considered a Bluetooth device. 多达八个蓝牙设备可以在被称为微微网的本地网络中相互通信。 Up to eight Bluetooth devices may communicate with each other in a local network is called piconet's. 在给定的微微网中,其中只有一个蓝牙设备是主设备,而其他都是从设备。 In a given piconet, only one Bluetooth device is the master, while the others are slaves.

[0045] 每次建立微微网时指定主设备的过程是动态过程。 [0045] The master device specified each piconet establishing process is a dynamic process. 蓝牙设备可以是多个微微网的一员,其中它可被指定为一个微微网的主设备,而作为另一个微微网的从设备。 Bluetooth devices may be more than one piconet, where it can be designated as a master of the piconet, but as a slave device of another piconet. 各蓝牙设备在决定是否要成为主设备时,可采用考虑不同变量的算法,这些变量是例如性能和功耗要求等。 Each Bluetooth device when deciding whether to become a master device, the algorithm can be considered different variables, these variables are, for example, performance and power requirements. 例如,由于发送信号以定位其它蓝牙设备来形成微微网需要利用发送带宽,蓝牙设备可被动地等待其他蓝牙设备来建立微微网。 For example, since the transmission signals to locate other Bluetooth devices to form a piconet need to use a transmission bandwidth, a Bluetooth device may wait passively for other Bluetooth devices to establish a piconet. 寻找其他蓝牙设备并与一个或多个蓝牙设备建立连接的蓝牙设备可被指定为这个微微网的蓝牙主设备。 Find other Bluetooth devices and Bluetooth devices with one or more Bluetooth devices may be designated as the master Bluetooth piconet. 多个相互连接的微微网可称为散射网(scatternet),例如,其中一个蓝牙设备可以是一个以上微微网的成员。 A plurality of interconnected piconets may be referred to as a scatternet (Scatternet), for example, where a Bluetooth device may be a member of more than one piconet.

[0046] 尽管图中只示出了单个微微网,但在包含多个微微网的系统中,蓝牙设备可能在一个微微网中作为主设备而在相邻微微网中作为从设备。 [0046] Although only a single piconet is shown, but the system comprises a plurality of piconets, the Bluetooth device may act as the master in one piconet and as a slave device in an adjacent piconet. 例如,蓝牙设备A可作为第一微微网Pl中的主设备,并作为第二微微网P2中的从设备。 For example, a Bluetooth device A may operate as a master in the first piconet Pl and P2 in the second piconet as a slave. 在另一实例中,蓝牙设备A可作为第一微微网Pl中的从设备,并作为第二微微网P2中的主设备。 In another example, the Bluetooth device A may operate as a master device from the P2, and as the second piconet of the first piconet Pl. 主设备,例如PC100可以与每一个从设备通信,例如膝上电脑110和PDA 120。 The master device 120 may be, for example, PC100 with each slave communication device, such as a laptop computer 110 and the PDA. 但是,从设备不能彼此直接通信。 However, from the device can not communicate directly with each other. 当主设备移出通信范围外时,该微微网即被破坏,直至另一个蓝牙设备建立微微网。 When the master device out of communication range, the piconet is destroyed until another Bluetooth device establishes a piconet.

[0047] 图2a是根据本发明的实施例使用的、带有蓝牙设备和WLAN设备的主设备的框图。 [0047] FIG 2a is a block diagram of the embodiment using the embodiment, the master device with a Bluetooth device and a WLAN device according to the present invention. 参照图2,示出了主设备200。 Referring to FIG. 2, the main device 200 is shown. 主设备200包括蓝牙通信设备210、WLAN通信设备212、处理器220以及存储器230。 The master device 200 includes a Bluetooth communication device 210, WLAN communication device 212, a processor 220 and a memory 230. 蓝牙通信设备210可以是蓝牙无线电,其中包括适当的逻辑、电路和/或编码,用于与其他蓝牙设备交换数据、命令和/或状态。 Bluetooth communication device 210 may be a Bluetooth radio, which may comprise suitable logic, circuitry and / or code for other Bluetooth devices to exchange data, commands and / or status. 蓝牙通信设备210包括处理器211。 Bluetooth communication device 210 includes a processor 211. WLAN通信设备212可以是WLAN无线电,包括适当的逻辑、电路和/或编码,用于与其他WLAN设备交换数据、命令和/或状态。 WLAN communication device 212 may be a WLAN radio, it may comprise suitable logic, circuitry and / or code, for exchanging data with other WLAN devices, commands and / or status. 处理器220可包括适当的逻辑、电路和/或编码,可以与蓝牙通信设备210和WLAN通信设备212交换数据、命令和/或状态。 The processor 220 may comprise suitable logic, circuitry and / or code, the data can be exchanged with the Bluetooth communication device 212 and the WLAN communication device 210, commands and / or status. 存储器230可包括合适的逻辑和/或电路,用于存储可被其它设备可能用到的信息,例如数据和/或代码。 The memory 230 may comprise suitable logic and / or circuitry that may be used to store information that may be used with other devices, such as data and / or code.

[0048] 在运作中,主机设备200可以是例如膝上电脑,通过蓝牙通信设备210来支持蓝牙功能,并通过WLAN通信设备212连接到LAN。 [0048] In operation, the host device 200 may be a computer such as a laptop, to support the Bluetooth communication device 210 via Bluetooth and connected to the LAN via the WLAN communication device 212. 处理器220可以是主设备200的处理器。 The processor 220 may be a processor 200 of the master device. 通过蓝牙通信设备210发送的应用程序可以是不同的应用程序,而不是通过WLAN通信设备212访问LAN的应用程序。 By application of the Bluetooth communication device 210 may transmit different applications, not the application to access the LAN via the WLAN communication device 212. 因此,在每个设备都要发送时,通信设备210和212发送的数据可能无法进行协调。 Thus, each device must send data 210 and 212 transmitted from the communication device may not be coordinated.

[0049] 当各通信设备都希望发送时,它会向其它通信设备断言信号线(signalline)。 [0049] When each communication device wishes to transmit all, it will assert a signal line to other communications devices (signalline). 例如,可以在蓝牙通信设备210与WLAN通信设备212之间使用2线信令协议(2_wiresignaling protocol)或者多线信令协议(multiwire signalingprotocol)。 For example, a 2-wire signaling protocol (2_wiresignaling protocol) between the Bluetooth communication device 210 with the WLAN communication device 212 or multi-line signaling protocol (multiwire signalingprotocol). 该信令可以由例如蓝牙通信设备210中的处理器211和/或硬件电路来完成。 This signaling can be done by, for example, the Bluetooth communication device 210 in the processor 211 and / or a hardware circuit. 将参照图2b和2c来更详细地描述该信令。 The signaling will be described in more detail with reference to FIGS. 2b and 2c.

[0050] 图2b是可与本发明的实施例结合使用的多线蓝牙/WLAN共存接口的框图。 [0050] FIG 2b is used in conjunction with the embodiment of the present invention is a block diagram of a multi-wire Bluetooth / WLAN coexistence interface. 参照图2b,示出了握手模块(handshaking block) 210a、以及蓝牙通信设备210与WLAN通信设备212 之间的WLAN_BUSY、BT_RF_ACTIVITY、BT_PRI0RITY_STATUS 以及FREQUENCY 信号。 Referring to Figure 2b, shows the handshake module (handshaking block) 210a, and a Bluetooth communication device WLAN_BUSY, BT_RF_ACTIVITY, BT_PRI0RITY_STATUS FREQUENCY signal between 212 and 210 and the WLAN communication device.

[0051] 握手模块210a包括合适的逻辑、电路和/或编码,用于与WLAN通信设备212通信。 [0051] handshake module 210a comprises suitable logic, circuitry and / or code for communicating with the WLAN communication device 212. 因此,蓝牙通信设备210可以向WLAN通信设备121指示,它正在与其它蓝牙通信设备通信,和/或它需要发送高优先级数据包。 Accordingly, the Bluetooth communication device 210 may indicate to the WLAN communication device 121, it is communicating with other Bluetooth communication device, and / or it needs to transmit high priority packets. 例如,处理器211和处理器220可控制握手模块210a。 For example, processor 211 and processor 220 may control the handshaking block 210a.

[0052] WLAN_BUSY 信号可由WLAN 通信设备212 控制,而BT_RF_ACTIVITY、BT_PRI0RITY_STATUS以及FREQUENCY信号可由握手模块210a控制。 [0052] WLAN_BUSY WLAN 212 may be a control signal communication apparatus, and BT_RF_ACTIVITY, BT_PRI0RITY_STATUS handshaking 210a and FREQUENCY signal may be a control module. FREQUENCY信号是可选信号。 FREQUENCY signal is an optional signal. 只要有蓝牙通信设备210进行的任何传输,握手模块210a可断言BT_RF_ACTIVITY信号,。 As long as there is any transmission for the Bluetooth communication device 210, the handshaking block 210a may assert BT_RF_ACTIVITY signal. BT_PRI0RITY_STATUS信号可被用于指示(signal)蓝牙通信设备210正在传输的特定蓝牙数据包的优先级。 The priority of a specific Bluetooth packet may be used to indicate BT_PRI0RITY_STATUS signal (Signal) Bluetooth communication device 210 is transmitting.

[0053] 为简便起见,图2b示出了那些到达和来自握手模块210a的信号可传输到WLAN通信设备212。 [0053] For simplicity, FIG. 2b shows those modules to and from the handshaking signal may be transmitted to the WLAN communication device 212 210a. 这些到达和来自握手模块210a的信号可与所使用的共存方法相关,且这些信号可被发送到或来自例如,报文传输仲裁(Packet TrafficArbitration,简称PTA)单元212a。 The signals to and from the handshaking block 210a may be associated with a coexistence method used and these signals can be transmitted to or from, for example, PTA (Packet TrafficArbitration, referred to as PTA) unit 212a.

[0054] 例如,PTA单元212a可以蓝牙从通信设备210和WLAN通信设备212接收信号,并仲裁在特定的时间段中哪个设备具有发送和/或接收的优先级。 [0054] For example, PTA unit 212a may receive signals Bluetooth communication device 210 and the WLAN communication device 212, and which device has transmitted the arbitration and / or priority received in a specific time period. PTA单元212a可与蓝牙通信设备210通信,以指示蓝牙通信设备210是否具有优先级。 PTA unit 212a may communicate with a Bluetooth communication device 210 to indicate whether the Bluetooth communication device 210 has a priority. PTA单元212a也与WLAN通信设备212通信,看它是否具有优先级。 PTA unit 212a may also communicate communication device with WLAN 212, to see if it has priority.

[0055] 因此,即使是BT_PRI0RITY_STATUS信号被断言,PTA 212a的仲裁算法也使WLAN_BUSY信号被断言。 [0055] Thus, even BT_PRI0RITY_STATUS signal is asserted, PTA 212a arbitration algorithm also WLAN_BUSY signal is asserted. 如果BT_PRI0RITY_STATUS信号未被断言,当WLAN通信设备212有数据要发送时,它可通过PTA 212a断言WLAN_BUSY信号。 If BT_PRI0RITY_STATUS signal is not asserted, when the WLAN communication device 212 has data to transmit, it may assert a signal WLAN_BUSY PTA 212a. 由于蓝牙通信设备210在发送低优先级的数据,它将停止发送数据。 Since the Bluetooth communication device 210 is transmitting low priority data, it stops sending data. 当下一个数据包即将进入WLAN频带时,握手模块210a断言可选的FREQUENCY信号。 When the next data packet is about to enter a WLAN frequency band, the module 210a asserts a handshake signal FREQUENCY optional. 因此,多线共存接口可被用于减轻蓝牙通信设备和WLAN设备同时发射时可能发生的干扰。 Thus, multi-wire coexistence interface may be used to alleviate interference that may occur when a Bluetooth communication device and simultaneously transmitting WLAN device. 将参照图3a和3b更详细地描述多线共存时的信令。 The multi-line signaling in the coexistence described in more detail with reference to FIGS. 3a and 3b.

[0056] 图3a是根据本发明实施例的、多线蓝牙/WLAN共存中的低优先级帧的示意图。 [0056] FIG. 3a is an embodiment of the present invention, a schematic view of a multi-wire Bluetooth / WLAN coexistence low priority frame. 参照图3a,示出了可由握手模块210a驱动的BT_RF_ACTIVITY信号和BT_PRIORITY_STATUS信号。 Referring to Figure 3a, and shows the signal BT_RF_ACTIVITY BT_PRIORITY_STATUS handshaking signal may be driven by module 210a. 握手模块210a可以是蓝牙通信设备210的一部分,蓝牙设备210可被配置为例如,蓝牙从设备。 Handshake module 210a may be part of the Bluetooth communication device 210, a Bluetooth device 210 may be configured, for example, from a Bluetooth device. 还示出了低优先级蓝牙帧的多个时刻T300…T305。 Also it shows a plurality of time frames of the low priority Bluetooth T300 ... T305. 对于低优先级帧,从设备的应答不必在应答数据的同一帧中进行发送。 For low-priority frames do not have to be transmitted in the same frame in the response data from the response of the device.

[0057] 在时刻T300,握手模块210a可断言BT_RF_ACTIVITY信号,以指示蓝牙帧将很快开始。 [0057] At time T300, the module 210a may assert BT_RF_ACTIVITY handshake signal to indicate that a Bluetooth frame will start soon. 蓝牙帧通常包括两个时隙。 Bluetooth frame typically includes two slots. 蓝牙主通信设备在帧的第一个时隙中发送数据。 Bluetooth master communication apparatus for transmitting data in a first time slot frame. 蓝牙从通信设备在帧的第二个时隙中将应答数据发送到蓝牙主通信设备。 Bluetooth will be transmitted from the second communication device in the time slot of the response data frame to the master Bluetooth communication device. BT_RF_ACTIVITY信号的断言可发生在蓝牙帧开始之前。 BT_RF_ACTIVITY asserted signal may occur before the start of the Bluetooth frame.

[0058] 时刻301可指示帧的第一时隙开始的时间。 [0058] The time frame 301 may indicate the start of a first time slot. 从时刻301到时刻303的时间段与帧的第一时隙大致相关,从时刻303到时刻305的时间段大致与帧的第二时隙相关。 Time period 303 from time 301 is substantially related to the first slot of a frame, generally related to the period from time 303 to time 305 of the second slot of the frame. 蓝牙通信设备210可以是从设备,它可在第一时隙的一部分中接收蓝牙主设备发送的数据。 Bluetooth communication device 210 may be, it may receive data sent by the Bluetooth master device in a portion of the first slot from the apparatus. 虽然帧通常包括两个时隙,但是也可包括两个以上的时隙。 Although the frame typically includes two slots, but may also include more than two slots. 因此,从时刻301到时刻303的时间段可包括多个时隙和/或从时刻303到时刻305可包括多个时隙。 Thus, from time to time period 301 may include a plurality of slots 303 and / or from time 303 to time 305 may comprise a plurality of slots. [0059] 在时刻302,BT_PRIORITY_STATUS信号可被断言,以向WLAN设备指示蓝牙通信设备210在传送数据。 [0059] 302, BT_PRIORITY_STATUS timing signal may be asserted to indicate to the WLAN device Bluetooth communication device 210 in transmitting data. 在传送数据后,握手模块2IOa可解除断言(deaSSert)BT_RF_ACTIVITY和BT_PRIORITY_STATUS信号,以指示当前帧的RF活动已经结束。 After the data transfer, the handshake module 2IOa releasably BT_RF_ACTIVITY and BT_PRIORITY_STATUS signal asserted (DEASSERT), to indicate that RF activity of the current frame has ended. 这可在时刻T304发生。 This may occur at a time T304.

[0060] 图3b是根据本发明实施例的、多线蓝牙/WLAN共存中的高优先级帧的示意图。 , High-priority frames schematic multi-line Bluetooth / WLAN coexistence in [0060] FIG. 3b is an embodiment of the present invention. 参照图3b,示出了可被握手模块210a驱动的BT_RF_ACTIVITY信号和BT_PRIORITY_STATUS信号。 Referring to Figure 3b, shows a signal and may BT_RF_ACTIVITY BT_PRIORITY_STATUS module 210a handshaking signals are driven. 握手模块210a可以是蓝牙通信设备210的一部分,蓝牙设备210可以是蓝牙从设备。 Handshake module 210a may be part of a Bluetooth communication device, the Bluetooth device 210 from device 210 may be a Bluetooth. 还示出了高优先级蓝牙帧的多个时刻T310…T317。 Also shows a plurality of high priority Bluetooth time frame T310 ... T317.

[0061] 从设备需要确认来自主设备的数据已经收到的数据帧,而正被确认的数据报文也在同一帧中,可以将这些数据帧指定为高优先级帧。 [0061] acknowledgment from the device requires a data frame data has been received from the master device, and the data being acknowledged message at the same frame, the data frames may be designated as high priority frame. 为了在蓝牙设备传输时没有干扰,向WLAN设备断言的高优先级允许WLAN设备中止传输。 For there is no interference in the transmission of a Bluetooth device, WLAN device to assert a high priority allows WLAN devices to stop the transfer. 特定数据包的高优先级的指定可相应地设计和/或实施。 Specify a particular high priority packet may be correspondingly designed and / or implemented. 某些被指定为高优先级的帧,例如,同步面向连接(SCO)帧可用于语音数据。 Some of which are designated as high priority frame, for example, synchronous connection oriented (SCO) voice data frames may be used.

[0062] 有些时候蓝牙从设备可知道某些帧在何时将会是高优先级帧。 [0062] There are times when a Bluetooth device can know from some frame of when would be a high priority frame. 例如,当蓝牙从设备处于监听(sniff)、保持(hold)或暂停(park)模式,它可知道何时是高优先级帧。 For example, when a Bluetooth device is in listening from (sniff), holding (HOLD) or suspension (Park) mode, to know when it is a high priority frame. 蓝牙从设备也可知道,例如,分配给SCO链路的帧是高优先级帧。 Bluetooth devices may also know from, for example, SCO link frame is assigned to a high priority frame. 数据包可在SCO链路中通过四种方法中的一种进行传输。 Packet may be transmitted by one of four methods in the SCO link. 第一种方法是HV3方法,其中每隔两个帧可被指定用于SCO数据包。 HV3 first method is a method in which every two frames may be designated for SCO packets. 第二种方法是HV2方法,其中每隔一个帧可被指定用于SCO数据包。 HV2 second method is a method in which every other frame may be designated for SCO packets. 第三种方法是HVl方法,其中每个帧都可被指定用于SCO数据包。 HVl third method is a method in which each frame may be specified for SCO packets. 第四种方法是DV方法,其中在同一数据包中发送数字和语音数据。 DV fourth method is a method in which the digital transmission of voice and data in the same packet. DV数据包可在每个帧中发送。 DV data packets may be transmitted in each frame. 因此,蓝牙从设备提前知道帧何时是高优先级帧。 Therefore, from a Bluetooth device to know in advance when the frame is a high priority frame.

[0063] 在时刻T310,握手模块210a可断言BT_RF_ACTIVITY信号,以指示蓝牙帧很快会开始。 [0063] At a time T310, the handshake module 210a may assert BT_RF_ACTIVITY signal to indicate that the Bluetooth frame will soon begin. 虽然蓝牙帧通常包括两个时隙,但是帧中也可以有两个以上的时隙。 While a Bluetooth frame typically includes two slots, but the frame may have more than two slots. 为了简洁起见,假设帧有两个时隙。 For simplicity, assume there are two frame slots. 帧中的第一个时隙可被蓝牙主通信设备用来发送数据。 A first frame slot may be a Bluetooth communication device for transmitting main data. 帧中的第二个时隙可被蓝牙从通信设备用来将应答和/或数据发送到蓝牙主通信设备。 The second frame slot may be used to transmit Bluetooth response and / or data to the master Bluetooth communication device from the communication device. BT_RF_ACTIVITY信号的断言可发生在蓝牙帧开始之前。 BT_RF_ACTIVITY asserted signal may occur before the start of the Bluetooth frame.

[0064] 时刻313指示帧的第一时隙的开始。 Start [0064] 313 indicates a time slot of the first frame. 从时刻313到时刻315之间的时间段与帧中的第一时隙大致相关,从时刻315到时刻317之间的时间段与帧的第二时隙大致相关。 313 from time to time between the time associated with the frame 315 is substantially in a first time slot, a time period between approximately 317 associated with the second slot of the frame 315 from time to time. 蓝牙通信设备210可以是蓝牙从设备,它可在第一时隙的部分中接收蓝牙主设备发送的数据。 Bluetooth communication device 210 may be a Bluetooth data, it may be received from the Bluetooth master device transmitted a portion of the first slot.

[0065] 在时刻311,BT_PRIORITY_STATUS信号可被断言,以向WLAN通信设备212指示下一帧是高优先级帧。 [0065] At time 311, BT_PRIORITY_STATUS signal may be asserted to indicate to the WLAN communication device 212 of the next frame is a high priority frame. 在时刻313,BT_PRIORITY_STATUS信号可被解除断言(deassert),以向WLAN通信设备212指示,蓝牙通信设备210不在这个时隙中传输。 At time 313, BT_PRIORITY_STATUS signal may be de-asserted (deassert), to indicate to the WLAN communication device 212, the Bluetooth communication device 210 is not transmitted in this time slot. 在时刻314,BT_PRIORITY_STATUS信号可被断言,以指示蓝牙通信设备210在这个时隙中传输。 At time 314, BT_PRIORITY_STATUS signal may be asserted to indicate that the Bluetooth communication device 210 transmitted in this time slot.

[0066] 在传输数据后,握手模块210a可解除断言BT_RF_ACTIVITY和BT_PR I0RITY_STATUS信号,以指示当前帧的RF活动结束。 [0066] After the data transmission, handshaking block 210a may de-assert BT_RF_ACTIVITY and BT_PR I0RITY_STATUS signal indicating the end of the current frame RF activity. 这可在时刻T316发生。 This may occur at a time T316. 在其他时刻,从设备可能不知道帧是否是高优先级帧,直至接收到来自主设备的数据之后。 At other times, the device may not know whether the frame is a high priority frame until after the arrival of data from the host device receives. 但是,接下来使用参照图3b所述的方法来指示当前帧是高优先级帧可能会太迟。 But then the current frame is used to indicate a high priority frame may be too late with reference to the method of FIG. 3b. 因此,需要另一种方法来指示这种情况,这种方法将参照图3c进行描述。 Accordingly, another way to indicate this situation, this method will be described with reference to FIG. 3c.

[0067] 图3c是根据本发明实施例的、改变多线蓝牙/WLAN共存中的从属帧的优先级的示意图。 [0067] Figure 3c is a schematic view of the priority according to an embodiment of the present invention, changing the multi-wire Bluetooth / WLAN coexistence dependent frames. 参照图3c,示出了可被握手模块210a驱动的BT_RF_ACTIVITY和BT_PRI0RITY_STATUS信号。 Referring to Figure 3c, and shows BT_RF_ACTIVITY BT_PRI0RITY_STATUS driving signals 210a may be a handshake module. 握手模块210a可以是蓝牙通信设备210的一部分,蓝牙设备210可以是例如,蓝牙从设备。 Handshake module 210a may be a Bluetooth communication device part 210 of the Bluetooth device 210 may be, for example, from a Bluetooth device.

[0068] 其中也示出了多个时刻T320…T326,以解释如何改变从属帧的优先级。 [0068] which also shows a plurality of timing T320 ... T326, to explain how to change the priority of slave frames. 本发明的实施例可用于在从诸如PCioo之类的蓝牙主通信设备接收数据后,将帧的优先级从低优先级改变为高优先级。 Embodiments of the present invention may be used in a communication from the Bluetooth master device PCioo receive data such as a priority of the frame changes from low priority to high priority. 特定数据包的高优先级的指定可相应地设计和/或实施。 Specify a particular high priority packet may be correspondingly designed and / or implemented. 高优先级帧可以是蓝牙从通信设备在与正被确认的数据报文相同的帧中发送应答数据包的帧。 High priority Bluetooth frame may be a frame response packet communication device transmits the same data packet being acknowledged frame from.

[0069] 在时刻T320,握手模块210a可断言BT_RF_ACTIVITY信号,以指示蓝牙帧很快会开始。 [0069] At a time T320, the handshake module 210a may assert BT_RF_ACTIVITY signal to indicate that the Bluetooth frame will soon begin. 虽然蓝牙帧通常包括两个时隙,但是帧中也可以有两个以上的时隙。 While a Bluetooth frame typically includes two slots, but the frame may have more than two slots. 为了简洁起见,假设帧有两个时隙。 For simplicity, assume there are two frame slots. 帧中的第一个时隙可被蓝牙主通信设备用来发送数据。 A first frame slot may be a Bluetooth communication device for transmitting main data. 帧中的第二个时隙可被蓝牙从通信设备用来将应答数据发送到蓝牙主通信设备。 The second frame may be a Bluetooth slots used to send response data to the master Bluetooth communication device from the communication device. BT_RF_ACTIVITY信号的断言可发生在蓝牙帧开始之前。 BT_RF_ACTIVITY asserted signal may occur before the start of the Bluetooth frame.

[0070] 时刻321可指示帧的第一时隙开始的时间。 [0070] The time frame 321 may indicate the start of a first time slot. 从时刻321到时刻324之间的时间段与中贞的第一时隙大致相关,从时刻324到时刻326之间的时间段与巾贞的第二时隙大致相关。 To the time period between approximately 324 and 321 related to the first time slot of Chen, a time period associated with the second slot is substantially between 326 towel Fok 324 from time to time.

[0071] 蓝牙通信设备210可被配置为从设备,它可在第一时隙的部分中接收蓝牙主设备发送的数据。 [0071] The Bluetooth communication device 210 may be configured, it may receive a master Bluetooth device from the transmitting device a first portion of the timeslot data. 处理器211或处理器220可解析所接收的数据。 Processor 211 or processor 220 may parse the received data. 它可确定这是高优先级帧。 It may be determined that this is a high priority frame. 因此,需要通知WLAN,使得蓝牙从通信设备210在下一个时隙发送应答时它将停止发送。 Therefore, notification WLAN, so that it stops sending the Bluetooth communication device 210 transmits a response from the next slot.

[0072]在时刻 322,BT_RF_ACTIVITY 信号被解除断言。 [0072] At time 322, BT_RF_ACTIVITY signal is de-asserted. 在时刻323,BT_RF_ACTIVITY 和BT_PRIORITY_STATUS信号被断言,以向WLAN通信设备212指示,蓝牙通信设备210需要传送高优先级数据。 At time 323, BT_RF_ACTIVITY BT_PRIORITY_STATUS signal is asserted, and to, the Bluetooth communication device 210 needs to transmit high priority data indicating the WLAN communication device 212. 在数据传输后,握手模块210a可解除断言BT_RF_ACTIVITY和BT_PRI0RITY_STATUS信号,以指示当前帧的高优先级RF活动结束。 After the data transfer, the handshake module 210a and may be de-asserted BT_RF_ACTIVITY BT_PRI0RITY_STATUS signal indicating a high priority event RF current frame ends. 这可在时刻T325发生。 This may occur at a time T325.

[0073] 图4是根据本发明实施例的、利用蓝牙和WLAN通信设备的多线共存接口来改变优先级的典型步骤流程图。 [0073] FIG. 4 is a, Bluetooth and WLAN communication device using a multi-wire coexistence interface embodiment of the present invention to change the priority of the exemplary steps of the flowchart. 参照图4,在步骤400中,蓝牙通信设备210确定下一帧是否是高优先级帧。 Referring to FIG 4, in step 400, the Bluetooth communication device 210 determines whether the next frame is a high priority frame. 例如,如果SCO链路被设置为使用HV3方法,则下一帧是高优先级帧。 For example, if the SCO link using HV3 method is set, then the next frame is a high priority frame. 因此,每个第三帧都是高优先级SCO帧。 Accordingly, every third frame is high priority SCO frames. 如果下一帧是高优先级帧,则下一步骤是步骤402。 If the next frame is a high priority frame, then the next step is step 402. 否则,下一步骤是步骤412。 Otherwise, the next step is step 412.

[0074] 在步骤402,蓝牙通信设备210可断言蓝牙RF活动信号,例如,BT_RF_ACTIVITY信号。 [0074] In step 402, the Bluetooth communication device 210 may assert a Bluetooth RF activity signal, e.g., BT_RF_ACTIVITY signal. 在步骤404,蓝牙状态/优先级信号可被断言,以指示下一帧的蓝牙RF活动是高优先级的。 At step 404, Bluetooth status / priority signal may be asserted, Bluetooth RF activity to indicate the next frame is a high priority. 被断言的信号可以是,例如BT_PRIORITY_STATUS信号。 Signal may be asserted, for example BT_PRIORITY_STATUS signal. 在步骤406,解除断言BT_PRIORITY_STATUS信号。 At step 406, signal de-asserted BT_PRIORITY_STATUS. 这样向并置(collocated) WLAN通信设备212做出指示,例如,蓝牙通信设备210即将接收蓝牙数据包。 Such is instructed to juxtaposed (collocated) WLAN communication device 212, e.g., a Bluetooth communication device 210 receives Bluetooth packets coming.

[0075] 在步骤408,BT_PRIORITY_STATUS信号被断言。 [0075] In step 408, BT_PRIORITY_STATUS signal is asserted. 这个信号被断言,以向并置WLAN通信设备212做出指示,蓝牙通信设备210接下来将会发射。 This signal is asserted to assert to the WLAN communication device 212 and make instructions, the Bluetooth communication device 210 will transmit next. 在步骤410,蓝牙通信设备210可解除断言BT_RF_ACTIVITY和BT_PRIORITY_STATUS信号,以向并置WLAN通信设备212指示,蓝牙帧结束。 In step 410, the Bluetooth communication device 210 may be de-asserted and BT_PRIORITY_STATUS BT_RF_ACTIVITY signal to indicate that the communication device is set to the WLAN 212 and the end of the Bluetooth frame. [0076] 在步骤412,可以是步骤400之后的下一个步骤,蓝牙通信设备210可断言BT_RF_ACTIVITY信号。 [0076] At step 412, may be the next step after step 400, the Bluetooth communication device 210 may assert BT_RF_ACTIVITY signal. 在步骤414,蓝牙设备可从蓝牙主设备接收数据包。 In step 414, the Bluetooth master Bluetooth device can receive data packets from. 由于BT_RF_ACTIVITY信号在步骤412中被断言后,BT_PRIORITY_STATUS信号可能没有被断言并接下来被解除断言,这将指示这个帧为低优先级帧。 Since the BT_RF_ACTIVITY signal is asserted in step 412, BT_PRIORITY_STATUS signal may not be asserted and de-asserted to be the next, this would indicate that the frame is a lower priority frames.

[0077] 在步骤416,蓝牙通信设备210可处理所接收的数据包,以确定它是否必须在例如在步骤414中接收的数据的同一帧中尽快回复。 [0077] In step 416 the data packet, the Bluetooth communication device 210 may process the received, to determine whether it must respond quickly in the same frame, for example, data received in step 414. 如果需要高优先级的答复,下一个步骤是步骤418。 If you need a high-priority response, the next step is step 418. 否则下一个步骤是步骤408。 Otherwise, the next step is step 408.

[0078] 在步骤418中,BT_RF_ACTIVITY信号可被解除断言。 [0078] In step 418, BT_RF_ACTIVITY signal may be de-asserted. 在步骤420,BT_RF_ACTIVITY和BT_PRIORITY_STATUS信号被断言。 In step 420, BT_RF_ACTIVITY and BT_PRIORITY_STATUS signal is asserted. 这向并置WLAN通信设备212指示,并置蓝牙设备接下来以高优先级进行发射。 This is set to the WLAN 212 and instructs the communication device, next collocated Bluetooth device to transmit a high priority. 然后蓝牙通信设备210发射答复数据包。 Bluetooth communication device 210 and then transmit the reply packet. 下一步骤是步骤410。 The next step is step 410.

[0079] 虽然本发明的实施例描述为以特定顺序断言共存信号,例如BT_RF_ACTIVITY和BT_PRIORITY_STATUS信号,但是本发明不必受限于此。 [0079] Although embodiments of the present invention are described as the coexistence signal asserted, and BT_PRIORITY_STATUS e.g. BT_RF_ACTIVITY signals in a particular order, the present invention is not necessarily limited thereto. 共存方法的规范可确定当一个信号相对于其他信号被断言或解除断言时的可允许范围。 Specification coexistence method may determine the allowable range when a signal is asserted or de-asserted with respect to other signals. 因此,可相应地设计和/或实施断言/解除断言时刻。 Thus, correspondingly designed and / or implemented assertion / deassertion time.
